' IMPROVED MODE OF CONSTRUCTING- IBU'llliIDII.,I.\`I'GIRONI'S The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may conce/rn:

Be it known that I, ISAAC S. MILLER, of the city, county, and State of New York, have invented a new and useful Improvement in Building, or Dwelling- Fronts; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters it in moulds, of any desired size, say, twelve inches in length, by tive inches in breadth, and one and a half inch in depth, 0r thickness, but of such form and construction that the brick, when baked, or pressed,will present, on the outside, a smooth surface, (Figure 1,) which may be made to imitate marble, Ohio, and brownstone, granite, bric-k, or other building-material, and, on the reverse, or inner side, will present an uneven surface,- (see Figure 2,) intersected by ridges, cut into the brick from the outer edges, or rim, to the centre, which ridges and outer edge, ela, are three-quarters 'of an inch in deptl1,leaving the intermediate space, or greater surface, to consist or" cavities, l1' b, of the same depth, for the reception of mortar, `when pressed against a vall, in building.

To insure perfect safety from bulging, or falling, in their use on high buildings, beside the mortar enter; ing the brick in nearly a dozen cavities, and thus binding it to the wall, I would anchor it to the wall by a thick, heavy wire, (Figure 3,) nine to ten inches in length, and which should lenter the. ridge about the centre ofthe brick.

Still greater eicicncy in this respect might be secured, by making the top of each brick convex and the bottom concave inform.'

C Zalm.

What I claim as my invention, and desire to secure by Letters Patent, is-

lhe use and application of brick, composition, or other stone, to the facings of buildings, or dwellings, substantially as herein described.
